Chapter 768 You fight for me
There are definitely more than one solution to achieve automatic control, but from the perspective of popularity, there is no better solution than single-chip microcomputer and PLC to achieve digital control. Analog circuit control is complex and expensive, and has high requirements for designers. Its functional performance is often outperformed by digital control systems. It is not the best choice unless necessary.

If a technology that is intended to be popularized requires people to show off their skills before it can be used normally, then it proves that this thing can never be popularized.

When it comes to PLC, it is essentially a highly reliable single-chip microcomputer system, so in the final analysis, it still has to be a single-chip microcomputer.

Moreover, the single-chip microcomputer required by PLC is not a high-end product in terms of specifications. Once the single-chip microcomputer is solved, it will be much easier to use PLC.

Gao Zhendong is very clear about the significance of single-chip microcomputers for popular automatic control systems. In fact, the leaders and chief engineers of the 12th Ministry of Machinery are also clear about it. Many automatic control systems only need some simple control functions, mainly to solve a problem that does not exist. For many systems, as long as this problem is solved, they will have great uses. As for how complicated and advanced they need to be, that is not the case.

For example, the DJS-59 composed of DJS-6108 to C61 is not unable to complete the function, but too overflowing. This overflow includes all aspects such as volume, weight, cost, function and performance, so it is impossible to be used on a large scale in simple industrial control. However, this single chip microcomputer is different.

I can use it casually without feeling bad about it. Even if I haven't reached the point where I don't feel bad about it yet, I can at least say that I can accept it.

Therefore, the people in the 12th Ministry of Machine Building were overjoyed about this matter. How many stuck technical transformation projects could be launched?

In fact, the significance of this thing is not the most important to the Twelve Machine Departments. Gao Zhendong was the first to invite the Twelve Machine Departments, mainly because they are the main force and the main person in charge of the promotion!
From now on, no matter which ministry needs to use this thing, it will be the work of the 12th Ministry of Machine Building.

As for the Defense Working Committee, they immediately began to consider which weapons and equipment this thing could be installed on!
At this time, they had already remembered that some comrades had consulted Gao Zhendong about certain equipment and had made reports.

"...Comrade Zhendong said that in this area, there will soon be control devices with greatly reduced size and weight that can be put into use..."

So this is where the words ended up! It really is a big reduction!
For the Defense Committee, the firmware IC plus this minimum system means that it can be installed in a portable air defense missile.

For the Defense Working Committee, the smallest guided weapon now is the portable air defense missile. As for solid anti-ship missiles, there is no problem at all.

A very magical feeling is that for the leaders of the Defense Work Committee, they don’t know what this thing can do when installed on those weapons, but they just think it is very important.

But the chief engineer is different. He can immediately come up with a lot of uses, more complex control algorithms, higher control accuracy, more flexible guidance strategies, stronger daily automatic detection and maintenance capabilities...

It can be said that installing this thing on guided weapons can not only enhance the core strike capability, but also effectively reduce maintenance costs, and even significantly reduce production costs. In particular, the more complex the function, the greater the cost of using analog circuits to achieve the same control function.

After all, for a single-chip microcomputer, as long as the program memory capacity is sufficient, changing an algorithm or a strategy is just a matter of a jump within the program. However, in analog circuits, it often means paying the price of an entire set of circuits.

As for the comrades of the Postal and Communications Commission, their idea was simple: well, let's modify the telegraph machine first, and then modify the fax machine~~~~~~
Yes, there were fax machines at this time, but the big problem was that they couldn't be used over regular phone lines, which greatly limited their use and popularity.

But they couldn't think of how to change it for a while. In short, as another major branch of information technology, the Postal and Communications Commission was very interested in the single-chip microcomputer. It didn't have strong capabilities, but it had a wide range of uses!

What is different from them is that as a core ministry that combines electromechanical and electronic equipment and studies and produces electromechanical equipment, the chief engineer of the 11th Ministry of Machine Building is more excited than anyone else.

"Chief Engineer Gao, what is the current production capacity of this thing? We'll take care of it!"

He asked hurriedly, not caring about anything else.

No matter how cheap this thing is, there won't be enough of it in the early stage. It's a new component and the production volume certainly can't be increased. However, the chief engineer of the 11th Ministry of Machine Building can think of so many pieces that have been "used" in advance.

After all, it is different from the previous ones. The previous ones are currently used more on production lines and production equipment. Even if the Defense Work Committee uses it on products, the amount used in their products is not large.

But it is different for the 11th Ministry of Machine Building. They can now think of which products to use on a large scale to enhance their capabilities, because strictly speaking, they are responsible for the research and production of electromechanical equipment and are the major users of automatic control systems.

Therefore, for them, now they can consume as many microcontrollers as they can, and there is no such thing as overcapacity at this time.

The person who came from the 11th Ministry of Machine Building was the chief engineer, but the leader did not have time to come in person. After hearing what the chief engineer said, the leaders of several other ministries looked at him unfriendlyly.

Hmm? What do you mean? You want to take down the whole thing right away?

"Comrade, I know you are anxious, but don't be anxious yet. We still need to sit down and discuss this matter slowly." The leader of the Defense Work Committee said with a smile. The leaders of the 12th Ministry of Machinery and the Postal and Communications Committee also looked in agreement.

It's bad enough. Meng was too reckless. His leader is not here, so he can't compete with these top executives for production capacity. Moreover, he asked for everything right away. This time they are alert, and they can't be persuaded back with just a few words.

The chief engineer of the 11th Ministry of Machinery now regretted that his superiors had not come over. He had no advantage at all at this time. "Haha, leaders, I just want to show my respect! My respect!"

The leader of the Defense Work Committee looked at him sideways and said, "Haha, I know you take it very seriously, but we take it very seriously too. We all work in ministries and commissions, so we all know who knows whom."

"Comrade Zhendong, this is called a single-chip microcomputer, right? This single-chip microcomputer is of great significance. Your production capacity should be considered and arranged by the Defense Work Committee." Cut off the firewood from the bottom of the pot! The other companies were dumbfounded.

Unlike the previous computers, most of which were not considered to be fully popularized and therefore there would be no competition for production capacity, this thing is to be promoted and used on a large scale, so competition for production capacity will naturally occur.

"Cough," the leader of the 12th Ministry of Machine Building coughed lightly.

By the way, this thing is produced in the 12th Ministry of Machine Building.

"How about this, our department will use Factory 1274 as a base to further expand the production scale of their integrated circuit workshop. The new production capacity will be mainly used for C6108, C6110, and this single-chip microcomputer... What is the name of this single-chip microcomputer, Comrade Zhendong?"

“C62D08。”高振东顺口起了个名字，倒是有点89C51的意思了，算是向51系列致敬吧。

"Oh, because it was born in '62, and the D stands for single-chip microcomputer? Not bad."

“No, 62 represents that it is a single-chip microcomputer, and D means that it only has running memory for the time being.” Gao Zhendong smiled. He planned to use 61 as a general-purpose CPU and 62 as a single-chip microcomputer, and keep doing it this way. This is called brand effect.

As for the single-chip microcomputer, Gao Zhendong wanted to integrate program memory in the chip later, that is, something like EEPROM, so the middle mark D is used to indicate that the current one only has running memory, to distinguish it.

"Oh, okay, and there is also this C62D08. The new production capacity will be used for the production of these three products." Don't force me. If you force me, we have the final say on how much was produced.

The leader of the Postal and Communications Commission stepped forward at the right time and said: "We still need to sit down and hold a meeting to discuss this matter. Plan, plan!"

Finally, several bigwigs discussed and agreed to hold a meeting, not only the people present today, but also comrades from other relevant ministries and commissions, to each put forward their needs and see how to divide this thing. The most important one among them is undoubtedly the 12th Ministry of Machine Building, after all, the production capacity is in its hands.

However, Gao Zhendong gave a wink to the Defense Work Committee. The leader of the Defense Work Committee saw it and laughed, thinking there was an ambush.

Originally, Gao Zhendong wanted to wait until the comrades from the 11th Ministry of Machine Building left before taking out the digital signal processor chip. But he changed his mind and thought that doing so would be a bit offensive. Anyway, it was not something that needed to be kept secret. The comrades from the 11th Ministry of Machine Building were also senior cadres, so there was no need to worry about the issue of awareness. If he was going to do it, he should do it all at once to avoid having to do it again later.

"Dear leaders and experts, in addition to the C62D08, there is another thing I would like to introduce to you. This is not as universal as a single-chip microcomputer, but it is still very helpful for specific work."

Gao Zhendong spoke very modestly, but no matter how modest he was, the Defense Work Committee and other departments immediately became extremely alert.

Gao Zhendong picked up a plastic box, inside of which was a chip about the same size as C62D08.

In fact, there is some difference in the area of ​​real silicon wafer DIE between the two, but Gao Zhendong uses the same size package, which is conducive to the common use in connector and circuit board manufacturing, so it looks like the two are basically the same size and shape. If you don’t look at the silk-screen model on the surface of the chip, you really can’t tell the difference.

"Zhendong, is this another single-chip microcomputer? Or?" The Defense Work Committee leader's eyes lit up. Now, he was very interested in anything that was an integrated circuit, and something that Gao Zhendong launched so grandly was even more worthwhile.

Gao Zhendong nodded: "It can be considered a single-chip microcomputer, but this single-chip microcomputer is quite special. It is specially used for digital signal processing."

Before anyone else could say anything, the chief engineer of the Postal and Communications Commission became excited.

"A single-chip microcomputer specifically used for digital signal processing? Is it the integrated digital signal processing board that the Institute of Communications obtained from you last time?"
